🔍 Product Description
S11 series is advanced designed to upgrade the former transformers in performance. It has compact structure which requires a much smaller space to install. Its noise has been lowed down and capacity of overloading has been enhanced. Comparing to S9 series, S11 series product decreased the loss of No-load by 30% and current of no-load declined to 45-80%.
Key Features:
- Low loss and small current in no-load condition. Low noise.
- No oil conservator, space-saving for installation.
- New Oil Gauge design makes sure it runs safely.
- Corrugated oil tank, good cooling performance and flexible in shaping.
- Cost-save, Long lasting service, Easy to maintain.
